1'0 aZZ whom it may concern:

Be it known that I, ANTON KRAPAOEK, a subject of the Emperor of Austria-Hungary, and a resident of Kreuzberg, Bohemia, Austriaddungary, have invented certain new and useful Improvements in Devices for Cleaning the Nozzles of VVater-Gages, of which the following is a specification.

My presentinvention relates toanimproved device for cleaning obstructed nozzles of water-gages, which may be easily and readily applied to any nozzle without danger.

In the accompanying drawings, Figure 1 is a longitudinal sectional View showing the device applied to the lower nozzle of a watergage. Fig. 2 is a corresponding top plan view. Fig. 3 is a side elevation. Fig. at is a section on line 00 of Fig. 2, and Fig. 5 shows a detail.

In the drawings, 1 represents the indicating-tube, the lower end of which is arranged in the stopper of the nozzle 2, secured by means of a flange 4 to the boiler. The cock 3 enables the passage from the boiler to the nozzle to be shut off. In Fig. 1 said cock is open, so that water can flow from the boiler into the glass tube 1. A cock 12 is provided for the purpose of shutting off or opening the exhaust-opening 6. For the purpose of enabling the bore 5, extending from the boiler to the gage-tube, to be cleaned from time to time the nozzle is provided with an opening to which access is given through the small nozzle 7. Said opening is normally closed by means of a screw.

WVhen it is desired to clean the nozzle of the water-gage, the cock 3 is turned off and the ordinary stopper is opened. Against the extension 7 I apply a tightening-ring 11, of rubber or similar material, through which is moved a wire 8, having an inner pointed end 9 and a small annular shoulder 10, adapted to fit snugly into the bore 5 and the bore of the opened cock 3. The opening in the rubber ring 11 is somewhat smaller than the shoulder 10, so that the wire cannot be completely withdrawn from the nozzle. The ruleber ring 11 is held in place on the metal disk 18 by means of screws 13 14 15 16 and a ring 17. The wire 8 is perfectly tightened in said metal plate 18 by means of a stuffing-box 19. Through said plate extend two yokes 20 and 21, the face ends of which are connected by cross heads 22 and 23, respectively. The

plate 18 is provided with four holes 24. 25 26 27 for the reception of said yokes, and the cross-heads 22 and are held in place on the plate 18 by means of set-screws 28 and 29, re spectively, the ends of which are adapted to WOIk freely in the plate 18, in which they are firmly held.

The cross-heads 22 and 23 are provided with larger openings 30 31 32 33 for the free passage of the ends of the yokes. Said openings are terminated by smaller openings 31 and 35, Figs. 3 and 5, the diameter of which is equal to the diameter of the reduced parts 36 and 37, Fig. 2, of said yokes.

hen it is desired to apply the rubber ring 11 firmly against the extension 7, all that is required is to tighten the screws 28 and 29, whereby the inner ends of the latter are firmly pressed on the plate 18 and on the rubber ring 11.

When the device is perfectly secured to the nozzle, the wire 8 may be moved therein without danger, the shoulder 10 thereon preventing said wire from being completely withdrawn from the nozzle.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a device for cleaning water-gages, a tightening-ring, means for clamping the ring to a nozzle, and a wire passing through the tighteningring, said wire having a pointed end, and a shoulder or enlargement back of the point, said shoulder being of a size to fit the bore in the nozzle, and larger than the bore in the tightening-ring, substantially as described.

2. A device for cleaning gage-nozzles, comprising an india-rubber tightening-ring se cured to a plate by a metal ring, yokes passing through the plate and engaginga portion of the gage-cock, means for clamping the tightening-ring to the nozzle, and a pointed wire, having a shoulder back of the point, said shoulder being of a size to fit the bore of the nozzle and larger than the bore in the tightening-ring, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of two subscribing witnesses.

ANTON KRAPAGEK.
